' E18 Claims.v (CL 5-2-30) The instant invention pertains tocertainnovel features of structure andmode of operation in bed-springsand comparable cushions,incorporating a series of upright spiralsprings, L

One feature of the invention resides in' anew or supplementalborder-wire arrangement which is securely held in place without directattachment to the erect spiral-springs with which itis associated. v

Another principle of the invention relates 'l30 a. so-calledplatform-top for the bed-spring or other cushion which is 'yieldinglysecured to such auxiliary border or marginal wire referred to. i

To allow those versed in, and acquainted with, this art to understandand appreciate the favor-s ableand valuable, characteristics. of thepresent invention, a current embodiment thereof has been illustrated indetail in the accompanying drawing, and, for simplicity, like referencenumerals have been employed in the severalviews of ,such drawing todesignate or denote the same structural parts or mechanical elementsa'nd from a comprehension of such construction other aims and objectsofthe invention will be perceived,

in this drawing- 7 i v v Figure 1 is a partial plan view of a bed-springor springcushion incorporating the structural features based upon :the.new invention;

Figure 2 is an enlarged, fragmentary, plan view of a small portion onlyof the bed-spring or cushion; and

Figure 3 is an edge view or elevation of that fragment of theconstruction shown in plan in ure 2.

Referring to these views of the drawing, it will .be readily observedthat the spring-cushion or bed-spring includes a number of suitablysupported, upright spiral-springs H, II shown di- "agrammatically,arranged in longitudinal and transverse rows, the top convolution orturn of l each such spring having its end knotted, at l2 around theadjacent portion of the wire constituting the spring.

These springs may be of tapered or hour-glass former of any otherappropriate conformation, but they are assumed to have the knots ortheir equivalents at the positions indicated, particularly withreference to the marginal springs.

As is clearly portrayed in Figure 1, the top or terminal rings of thesesprings are connected togetherin any approved fashion as by intersectingor crossing helical-springs l3, l3,

A continuous border-wire ll extends around the top margin of thestructure, and, in the plane of the upper surface of the springs andsuch volution, as is clearly illustrated in Figure 3.

border-wire, in a manner well-known, has spacedapart, inner recesses orcavities receiving the outermost parts of the top convolutions orterminal 'rings of the marginal springs, such border- 3N wire atitscavities being deformed or clamped 5' at least in part inwardlyaround the end convolutions of the springs tohold them firmly in place,there being nothing new novel in that particular fastening means.

It istofbe noted, as shown in Figure, 1, that the stated knots orconnections of all of the marginal springs are aligned along the sidesand ends of its ends connected together in anyapproved or suitablemanner at It], thus providing an endlessorfunbroken member which extendsaround the bed-spring beneath thetop rings or coils thereof and justoutside of the knots I2 with whichthey may be incontactfor out ofcontact, but, in any: case, such supplementary border wire l5, at .eachspring is wedged between its terminal-ring and the wire of the nextlower conlhus such additive or subsidiary boundarywire I I5, so far asinward shifting or movement thereof is concerned, is fixed with relationto all of the marginal spiral-springs and through their top rings orcoils is secured firmly to the main or principal border-wire Ill.

The platform-top for the bed-spring is composed of flat-narrow,longitudinal and transverse, metal bands or straps l6 and I1,respectively, located just above andbearing on the tops of the erectspiral-springs, with their points of, crossing in register with the axesof such springs.

The specified members l6 and I1 terminat 40 short of the innerborder-wire l5 and their ends are connected to such element I5 by shorthelical-springs I8, I83, whereby the load strains impose-d on thesuperposed platform are transmit- I ted to the inner border-wire l5 andthrough the end-ringsof the spiral-springs to the outer border-wire l4.

The new and improved spring cushion or bedspring has its platform-topyieldingly joined to the multiple border-wires and by reason of therelation of the inner border-wire to the knotted portions of thespiral-springs, it cannot be pulled inwardly by the load on the platformand such inside border-wire is assisted in performing such v55 30 of thecushion being in substantial alignment for each side andeach end ofthecushion, and a tions of the wires and just outside said connecof thecushion being insubstantial alignment for each side and each end ofthe'cushion, a main border-wire extended around the cushionsubfunctionby its connection to the outer borderwire through the end-rings of thesprings.

The bed-spring illustrated and described may have any type of supportfor the spiral-springs which seems to be desirable, but, in some casesat least, it is feasible to make the bottom and the topof the springcushion alike or substantially' identical.

This invention is presented and defined in the appended claimswhichshould be construed or interpreted as generically as permitted by thestate of the prior art and yet preserve their validity, but, it is to beremembered that the in- 1 vention is not necessarily limited orrestricted to the precise and exact structural details referred tobecause various changes and modifications may be resorted to withoutdeparture from the principles underlying the invention and without theloss or sacrifice of any material advantage incident to the employmentof the in-" vention. r
